I purchased this from a shop called "Rakuten's Suteki Taiken." It has a zipper at the chest, making nursing easy. The waist has two buttons on each side, allowing for adjustment. The skirt is also double-layered, giving it a high-quality look. It can be worn by pregnant women, and even the S size had room. I wore it only once for Shichi-Go-San (a Japanese festival for children). It can also be worn for ceremonies such as entrance and graduation ceremonies. I've set the product condition to be strict because there was a near-problem once. If you have any questions, please comment. Product Description: Perfect as nursing wear for formal occasions! A beautiful silhouette formal dress. This is maternity formal wear that supports both before and after childbirth with a nursing opening. It has a beautiful silhouette and is also a must-have item with functionality. You can enjoy a comfortable fit and a beautiful silhouette.
